Other causes of corneal ulcers include: Abrasions or burns to the cornea caused by injury to the eye. Scratches, scrapes and cuts from fingernails, paper cuts, makeup brushes and tree branches can become infected by bacteria and lead to corneal ulcers. Burns caused by caustic chemicals found in the workplace and at home can cause corneal ulcers.
Tiny tears to the cornea may also cause corneal ulcers. These tears can come from direct trauma, scratches or particles such as sand, glass or small pieces of metal. Such injuries damage the cornea and make it easier for bacteria to invade and cause an ulcer.
